Yes RWS brass is good. You might want to take a magnet to them. Some if I remember correctly 9 mm were only brass plated steel. RWS 45 brass is very good. S&B brass does have tight primer pockets. The ones with the red sealant on the primer I can load with Winchester primers. After a few reloads they work just like once fired Winchester. Winchester brass is also good. I can reload it many times before it starts to fail. I'll load Remington brass, but, it doesn't seem to hold up as well as Winchester does. Federal and Blazer brass seem to reload about an equal number of times and longer then Remington. I also don't care too much for WCC brass but it too get loaded again by me. Steel, Aluminum and A-Merc all go to the trash.
